Title: Container for pre-cooked foods with an inner lid or tray inside an outer lid
IPC: B65D81/32
Filed: 1975-10-31
Abstract: 1530605 Cooking containers NISSIN SHOKUHIN KAISHA Ltd 31 Oct 1975 [16 May 1975 19 April 1975 13 Dec 1974] 45417/75 Heading A4A [Also in Division B8] A container for in situ heating or reconstituting of food, e.g. rice, comprises a receptacle 8 holding the rice, an outer peelably-removable lid or cover 7, and an inner flanged plug-in removable lid 11, separated openings 12 and 13 being provided in the bottom wall of the lid and/or defined between peripherally-arranged axially-extending grooves in the flanged lid and the inner surface of the receptacle, Figs. 2-5 (not shown), so that hot water may be poured into the receptacle to heat the rice through some of the openings and/or grooves whilst leaving others free to vent. The water may subsequently be drained off through the openings and/or grooves. The inner lid forms an auxiliary compartment for subsidiary food B and is retained by a sealing cover 7 peelably-adhered to the top of the receptacle. On partial or complete peeling-off of the cover, the subsidiary food is removed and hot water is poured into the lid, the water passing into the receptacle via the holes. Surplus water is drained off through the group of openings 12 on one side of a partition 1. The opening 13 on the other side of the partition serves as a vent. In another embodiment, (Figs. 2 and 3), peripheral axially-extending large and small grooves 17 and 18 are formed in the flange of the lid and cooperate with the wall of the receptacle to define water inlet/outlet channels and vents 19 and 20 respectively. The lid is filled with soup, sauce or a granulated material and sealed independently by a closure 21, and the lid/receptacle combination is scaled by a peelable lid 7a. In a final embodiment, (Figs. 4 and 5), openings in the lid are formed by slots 25 and 26, the slots 26 being formed in bottom recesses 24, which prevent jamming of stacked lids, and peripheral lid grooves 28 cooperate with the receptacle to form passages 29. Water passes into the receptacle through the slots whilst air is vented through the passages. Since the slots 25 are disposed at a higher level than the slots 26, the former may also provide venting.

Abstract: 1,004,379. Crimping yarn. MONSANTO CO. Nov. 18, 1963 [Nov. 23, 1962], No. 45474/63. Headings D1F and D1W A molecularly orientable synthetic continuous filament yarn 3 made from a thermoplastic polymer is passed through a heat-stretch zone formed by rolls 1, 2, heated draw pin 8, and crimp rolls 12, 15. Roll 12 is movable between selectively variable crimping and non-crimping positions. It is resiliently urged away from roll 15 by spring 23 but urged into the crimping position when cylinder 22 is connected to the air supply 33 through three way valve 29 which is alternately turned on and off by timer 31. A controller 35 varies the pressure of the air supplied to cylinder 22 and thus the amplitude of the crimps. The apparatus can thus produce a continuous, uniformily or variably cimped yarn, or an intermittently, uniformly or variably crimped yarn with a regular or irregular interval pattern. The latent crimp produced by rolls 12, 15 may be developed by passing the yarn on a conveyer 42, Fig. 6 (not shown), through an oven.

Abstract: 1325060 Cigarette tube making machine A KASTNER 2 Oct 1970 [6 Oct 1969] 46914/70 Heading A2C [Also in Division F2] Filter plugs are inserted onto a continuous strip of cigarette paper 16 at spaced distances therealong during its formation into a continuous rod, and the formed rod is severed between filter plugs into double cigarette tube lengths which are subsequently bisected through their filter plugs to form single length paper cigarette filter tubes. The paper strip 16, after the application of a continuous line of adhesive along one of its edges by a disc 30, is fed on an endless flexible belt 2 through a former 24 which it enters at a point 26. Filter plugs are fed, by a reciprocating rod 36, onto the paper strip 16, through an injection tube 28 which projects into the former 24 to a point approximating to where the paper 16 is formed into a circular cross-section. Double length filter plugs are inserted into the injection tube 28 through a slot-shaped aperture 46. Preformed filter plugs may be used or, as shown in Fig. 5, a continuous strip of filter material 50 may be cut along the dotted line 52 to form single strips 50' which are each moved transversely in turn by a plate 54 and then compressed into plugs and inserted into the injection tube 38 through the aperture 46 by a compresser 56. Adhesive for holding the filter plugs within the formed filter tubes is applied, either to the plugs by a nozzle 66 through an opening 68 in the injection tube 28. or to the paper strip 16 by one or more rollers having portions of their peripheries cut away and which are mounted adjacent to the adhesive applying disc 30.

Filed: 1973-10-09
Abstract: 1452284 Camera which automatically switches to flash WEST ELECTRIC CO Ltd 9 Oct 1973 [13 Oct 1972 20 Oct 1972 (3)] 46996/73 Heading G2A [Also in Division H2]  Photographic flash apparatus includes a transistorized D.C.-D.C. converter 27, supplied from a D.C. source 28 and having a primary discharging capacitor 14, the D.C. source 28 comprising a plurality of rechargeable secondary cells 4, 5 with a series/parallel switch 6 arranged so that the cells 4, 5 are charged in parallel from a primary cell 1 and discharged in series into the D.C.-D.C. converter 27. As described, a pair of nickel cadmium batteries 4, 5 are normally connected in parallel by means of switch 6 and are kept charged by means of a penlight LeclanchÚ manganese battery 1. The relative voltages of the batteries 1, 4, 5 is such that when fully charged, the batteries 4, 5 draw no more than the normal leakage current from the primary battery 1. The reflected light from the subject is received by a photo-conductive element 19 of a shutter timing circuit and if the light is insufficient, a warning lamp 24 lights up and a switch 20, closed by depression of the shutter release, allows transistors 21 to energize a relay 26 which completes the base circuit of the transistor oscillator 10 so as to charge capacitor 14 and fire the discharge flash tube 23. Further switches 6, operated by the shutter release before switch 20, connect batteries 4, 5 in series for this operation. The switching of the transistor oscillator 10 by contacts in the base circuit reduces the wear on the contacts. In Fig. 9 (not shown) the oscillation is normally inhibited by means of a thyristor connected between base and emitter, the thyristor being turned off by means of an auxiliary transistor turned on in response to reduced ambient illumination. Fig. 10 (not shown) depicts construction of switch contacts suitable for operation by the shutter release.

Abstract: 1,016,774. Axial-flow fans. ENGART FANS Ltd. and HESTON RUBBER CO. Ltd. Dec. 9, 1963 [Dec. 19, 1962], No. 48061/62. Heading F1C. A fan blade 11, particularly for an axial-flow fan, is constructed from a non-metallic electrically conducting substance bonded to an inner metallic reinforcement 12 which protrudes from the blade root 11a to provide a fixing means for attachment of the blade to a runner hub 10. This prevents the build-up of static electricity and thereby the avoidance of sparking due to discharge thereof, which sparking is particularly dangerous in fans handling explosive or inflammable gases, for example those used in coal mining. The non-metallic electrically conducting substance is also non-combustible and may be of neoprene rubber and carbon black. It may be moulded around and chemically bonded to the reinforcement 12 which may be apertured and/or roughened or serrated. The reinforcement may be a flattened mild steel tube or a solid forged steel insert. The blade 11 is secured to the hub 10 in an angularly adjustable manner by a nut 14 engaging a stud 13 screwed, welded or formed on the reinforcement 12. The hub 10 may be provided with a non-metallic cover. In an alternative construction the inner reinforcement consists of a metal plate corresponding in shape to the profile of the blade.
